Jellyfish

36 Calories per 100g

A jellyfish is a soft-bodied, free-swimming marine animal with a gelatinous umbrella-shaped bell and trailing tentacles, typically transparent or bluish in color. Jellyfish are found in every ocean, from the surface to the deep sea. Some jellyfish are also capable of living in freshwater.

Jellyfish have been on Earth for at least 500 million years, and possibly even longer. They are among the oldest multi-organ animal groups on the planet. Jellyfish are thought to have evolved from a group of colonial organisms called comb jellies.

Jellyfish are not fish, but rather are classified as invertebrates, meaning they lack a backbone. However, they are still members of the animal kingdom. Jellyfish are made up of about 95% water. They average about 2% solid matter, which contains their digestive organs, nerves, and a simple muscle layer.

The bell-shaped body of a jellyfish is called the umbrella, or exumbrella. The umbrella is surrounded by a thin, transparent membrane called the epidermis. The epidermis is supported by eight radial canals, which extend from the margin of the umbrella to the center.

The umbrella contains the jellyfish's mouth, which is also its anus. Jellyfish do not have a brain or centralized nervous system. Instead, they have a network of nerves, called a nerve net, located in the epidermis. This nerve net allows the jellyfish to sense stimuli, such as the touch of a prey animal, and respond accordingly.

Jellyfish have two main types of tentacles: feeding tentacles and stinging tentacles. Feeding tentacles are used to capture prey and bring it to the mouth. Stinging tentacles are used to defend the jellyfish from predators and to capture prey.

Jellyfish use a variety of methods to capture prey. Some jellyfish simply wait for prey to swim into their mouth. Others actively pursue prey. Still others use their stinging tentacles to paralyze prey so that it can be more easily consumed.

Jellyfish are mostly passive predators, meaning they do not actively seek out prey. However, some species of jellyfish are known to be aggressive and will attack other animals, even humans, if they feel threatened.

Jellyfish are carnivores, meaning they eat other animals. Their diet consists mainly of small fish, crustaceans, and other invertebrates. Jellyfish use their tentacles to sting and paralyze their prey. They then bring the prey to their mouth, where it is pulled inside and digested.

Jellyfish are capable of reproducing both sexually and asexually. In sexual reproduction, male and female jellyfish release sperm and eggs into the water, where fertilization occurs. The fertilized eggs develop into larval stages, which eventually settle to the bottom and metamorphose into adult jellyfish.

Asexual reproduction occurs when a jellyfish splits into two or more parts, each of which grows into a new jellyfish. This process, called fragmentation, is common among many species of jellyfish.

Jellyfish are found in all oceans of the world, from the surface to the deep sea. They are also found in some freshwater lakes and rivers. Jellyfish are most common in warm, tropical waters.

Jellyfish are an important part of the marine food web. They are a food source for many animals, including fish, turtles, and seabirds. Jellyfish are also known to play an important role in controlling the populations of other animals, such as zooplankton.

Jellyfish are a fascinating and unique group of animals. They have been on Earth for millions of years and are found in every ocean. Jellyfish are beautiful, but also dangerous creatures. They are an important part of the marine food web and play a crucial role in controlling the populations of other animals.
